Abstract
Official abstract text for this publication.
A method is presented for transmitting uplink control information and a mobile station. The method for transmitting the uplink control information includes: adding padding bits to initial control information to generate uplink control information, where the initial control information includes first information having a same number of bits for RANKs of different channel matrices and second information having a same or different number of bits for RANKs of different channel matrices; and transmitting the uplink control information.
First claim
Opening claim text (preview).
What is claimed is: 1. A terminal, comprising: a control unit configured to generate uplink control information, wherein the uplink control information includes first information and second information, and the first information has a same number of bits for RANKs of different channel matrices; and a transmitting unit configured to transmit the uplink control information, wherein the first information includes a RANK indicator and a CSI-RS resource indicator, and the second information includes a channel quality indicator and a precoding matrix indicator. 2. A method performed by a terminal, comprising: generating uplink control information, wherein the uplink control information includes first information and second information, and the first information has a same number of bits for RANKs of different channel matrices; and transmitting the uplink control information, wherein the first information includes a RANK indicator and a CSI-RS resource indicator, and the second information includes a channel quality indicator and a precoding matrix indicator. 3. A base station, comprising: a receiving unit configured to receive uplink control information, wherein the uplink control information includes first information and second information; and a control unit configured to determine the first information has a same number of bits for RANKs of different channel matrices, wherein the first information includes a RANK indicator and a CSI-RS resource indicator, and the second information includes a channel quality indicator and a precoding matrix indicator. 4. A system comprising a terminal and a base station, wherein the terminal comprises: a control unit configured to generate uplink control information, wherein the uplink control information includes first information and second information, and the first information has a same number of bits for RANKs of different channel matrices; and a transmitting unit configured to transmit the uplink control information; and the base station comprises: a receiving unit configured to receive the uplink control information, wherein the first information includes a RANK indicator and a CSI-RS resource indicator, and the second information includes a channel quality indicator and a precoding matrix indicator.
